Association of hypodontia with stages of dental development for each of the seven left mandibular teeth, expressed by estimates of b-coefficients and 95 % confidence intervals; assessed from ordinal regression model using developmental stage (A/1, B/2, C/3, D/4, E/5, F/6, G/7, H/8) as a dependent variable and hypodontia status (No-ref., Yes) as a determinant in Model 1. Model 2 was additionally adjusted for age, gender, and study population. Model 3 was adjusted for variables used in previous model and additionally for ethnicity and maternal age at birth of a child
